I graduated college.
Calloo, callay, O frabjous day! At last, I have found someone else who knows the meaning of the verb graduate. I also, on hearing the quoted statement, have had this mental picture of drawing neatly spaced lines on a college building (like the school which talks to Sally in Peanuts) with one of those strange wire things which looked like a large fan, which held 5 pieces of chalk and which was used to draw a staff on the blackboard in music class. Wonder if there are any of those things left in the world? There are certainly very few music lessons in public schools.
